The specific meaning of the above terms in the present invention can be understood based on the specific situation by those skilled in the art.

First, referring to fig. 1, an air cleaner 100 of the present invention will be explained. The air purifier in this embodiment is an air conditioning device that sucks indoor air into the interior and then filters the air and blows the air out, thereby improving air cleanliness. In this air purifier, except filtering capability, still discharge to indoor again after humidifying the air through setting up humidification unit, realize the function of humidifying indoor air. In addition, the air purifier 100 of the present invention may purify other gases in addition to the air.

The air purifier 100 includes a frame 110, an air blowing unit 120, a filter unit 130, and a humidifying unit 140 constituting an air purifier housing.

The frame 110 is a polyhedron having a hollow box shape and forming a housing of the air cleaner 100. In the mounted state of the air cleaner, the frame body 110 includes a top plate 111 (frame body top plate), a bottom plate 113, and a side wall 112, wherein the top plate 111 and the bottom plate 113 are disposed opposite to each other in the vertical direction, and the side wall 112 connects the top plate 111 and the bottom plate 113. The top plate 111 and the bottom plate 113 are in an approximately parallel state in the vertical direction, and at least a part of the projection of the top plate 111 on the bottom plate 113 along the vertical direction covers the bottom plate 113. The above-mentioned installation state refers to a state that enables the air purifier to normally operate, for example, a state that the air purifier is installed or placed on the ground. The side walls 112, the top plate 111, and the bottom plate 113 form a hollow approximately rectangular parallelepiped box having an internal space. The inner space accommodates the air supply unit 120, the humidification unit 140, and the filter unit 130.

Referring to fig. 1, 3, 4 and 5, the top plate 111 is provided with an air outlet 111a, a water inlet 111B, a water guide groove 111c and an operation panel B. The outlet 111a is used to blow out the purified and/or humidified air from the inside of the housing 110. Specifically, a plurality of elongated support ribs are arranged on the frame top plate 111, the plurality of elongated support ribs form a grid, and gaps between the support ribs form the air outlet 111 a. It should be noted that the "gaps between the support ribs form the air outlets" herein does not mean that all the gaps form the air outlets 111a, and the specific position and size of the air outlet 111a on the top plate 111 may be determined according to the position of the snail shell exhaust outlet 1205 or the air outlet direction, etc. described later. The water filling port 111B, the water chute 111c, and the operation panel B will be described in detail later.

The side wall 112 is a wall having a curved surface for connecting the top plate 111 and the bottom plate. The side wall 112 includes a front panel 112a and a rear panel 112 b. The front panel 112a and the rear panel 112b are detachable and have an air inlet 110z for air to enter the frame 110. The left and right end portions of the front panel 112a and the left and right end portions of the rear panel 112b are connected by the side walls 112. The front panel 112a and the rear panel 112b are arranged at the same time, so that bidirectional air inlet can be realized. Of course, in one example, only the front panel 112a or only the rear panel 112b may be provided.

An air duct for guiding air from the inlet 110z to the outlet 111a is formed in the frame 110. The components in the air duct are described below.

The air supply unit 120 is arranged in the frame 110 and comprises a bidirectional wind wheel 1201, a single-shaft motor 1202 and a snail shell 1203 arranged in an air duct. The snail shell 1203 is internally provided with a cavity for accommodating the single-shaft motor 1202 and the bidirectional wind wheel 1201, the cavity is formed into a circle, the diameter of the cavity is larger than the external diameter of the bidirectional wind wheel 1201, the cavity surface is provided with openings towards two sides of the front panel 112a and the rear panel 112b, the two openings form a snail shell air inlet 1204 for air to flow into the snail shell 1203 and are respectively communicated with the air inlets 110z of the front panel 112a and the rear panel 112b, and air inlet on two sides of the air purifier is realized. The downstream side of the bidirectional wind wheel 1201 in the air flowing direction is provided with an opening, namely a snail shell air outlet 1205, for air to flow out from the snail shell 1203. The output shaft of the single-shaft motor 1202 is connected with the shaft hole of the bidirectional wind wheel 1201, and the bidirectional wind wheel 1201 is rotated by the single-shaft motor 1202, so that air is guided to enter the air inlet 1204 of the snail shell from the air inlet 110z, then flows to the air outlet 1205 of the snail shell, and finally is blown out through the air outlet 111 a.

In addition, referring to fig. 11 and 12, in general, in order to supply the indoor air to each corner of the room as much as possible, the outlet 111a of the frame 110 is generally set to be large, and the area of the snail shell exhaust outlet 1205 is small compared to the outlet 111 a. Therefore, in the process that the air is blown out from the snail shell air outlet 1205 and flows to the air outlet 111a, turbulent flow is easily generated due to sudden change of the size of the air channel, so that the air volume is reduced, and the noise is increased. Therefore, an air guiding plate C may be disposed between the snail shell air outlet 1205 and the air outlet 111a, and the air guiding plate C has an inclined surface for guiding air flowing from the snail shell air outlet 1205 to the air outlet 111 a. Through this inclined plane for air smoothly flows to air outlet 111a along the inclined plane after blowing out from snail shell air outlet 1205, thereby reduces the sinuous flow, improves the amount of wind, noise reduction. In one example, the air deflector C may not be provided.

Referring to fig. 1, the filter unit 130 is provided in the frame 110 to filter air guided from the inlet vent 110z to the outlet vent 111 a. The filter unit 130 serves as a member for improving air cleanliness. In one example, the filtering unit 130 may be a screen, which may directly intercept dust or the like. Of course, the filter unit 130 may have other structures, such as a high voltage generator, which ionizes the gas to electrically adsorb the dust particles to the electrodes. In this embodiment, the filter unit 130 is two filter screens for dust collection and deodorization, which are respectively located in the space between the air inlets 110z of the front panel 112a and the rear panel 112b and the snail shell air inlet 1204 to filter the air entering the frame 110 from the air inlets of the front panel 112a and the rear panel 112 b. Of course, in the example where only the front panel 112a or only the rear panel 112b is provided, correspondingly, only the filter unit at the front panel 112a or only the filter unit at the rear panel 112b may be provided.

The humidification unit 140 is provided in the frame 110, and includes: two humidification curtains 1401 respectively disposed at downstream sides of the two filter screens, two first water receiving trays 1402 respectively disposed below the two humidification curtains 1401, a detachable water tank 1403 disposed at one side of the air blowing unit 120, and a second water receiving tray 1404 disposed below the water tank 1403. In this embodiment, the second drip tray 1404 and the two first drip trays 1402 are integrally formed. The water tank 1403 has a water inlet 1405 at an upper portion thereof, the water inlet 1405 communicates with a water inlet 111b provided in the frame top plate 111, and a user injects water (or other liquid) into the water inlet 111b to cause the water to flow into the water tank 1403 through the water inlet 111b of the frame top plate 111 and the water inlet 1405 of the water tank. In addition, the user can also add water by removing the water tank 1403. The water in the water tank 1403 flows to the second water receiving tray 1404 and then flows to the two first water receiving trays 1402. The humidifying curtain 1401 can rotate, at least one part of the humidifying curtain 1401 is soaked in the first water receiving tray 1402 in the rotating process, the humidifying curtain 1401 absorbs water in the first water receiving tray 1402 and then rotates into an air duct, and air passes through the humidifying curtain 1401 to be humidified.

The humidifying unit 140 is a member for humidifying air, and may be a device for breaking water into atomized particles and mixing the particles with air, a humidifying filter screen for humidifying air after passing through, or the like, in addition to the humidifying curtain.

In summary, when the air cleaner is in operation, air is sucked by the bidirectional wind wheel 1201, enters from the air inlet 110z provided in the front panel 112a and the rear panel 112b, passes through the filter unit 130, the snail shell 1203 and the bidirectional wind wheel 1201 in sequence, and is blown out of the housing through the air outlet 111a provided in the top plate 111. Thus, the air purifier supplies air with high humidity by humidifying the air and blowing the air.

Referring to fig. 2 to 6, the water inlet 111B and the operation panel B will be described in detail. In addition to the air outlet 111a, a water guide groove 111c (water guide structure) and a partition plate 111e having a predetermined height and separating the air outlet 111a and the water guide groove 111c are provided on the frame top plate 111. That is, the partition plate 111e is provided with an air outlet 111a at one side and a water guide groove 111c at the other side. The water guide groove 111c is a groove portion surrounded by the partition plate 111e and the periphery of the top plate 111 and capable of accommodating a certain amount of water, and extends from one side of the top plate 111 to the other side opposite to one end of the top plate 111. The water injection port 111b may be provided at any position in the water guide groove 111c on the premise that the water injection port 111b communicates with the water inlet 1405 of the water tank 1403. In the present embodiment, the water injection port 111b is provided at an end of the water guide groove 111 c. The water guide groove 111c is inclined downward from the outer peripheral side of the water filling port 111b toward the water filling port 111b side to form an inclined surface (that is, the water guide groove 111c includes a water guide surface extending gradually obliquely downward from a position distant from the water filling port 111b to a position close to the water filling port 111 b), so that the water in the water guide groove 111c is guided to flow toward the water filling port 111b along the inclined surface. That is, when a user adds water to the water inlet 111b, the user can pour water into the water inlet 111b by pouring water into the water guide groove 111c having an area larger than that of the water inlet 111b without aligning the water with the water inlet 111b, thereby improving convenience of water addition and preventing the user from slipping down due to splashing of water without completely aligning the water with the water inlet 111 b. Further, since the partition plate can partition the air outlet 111a and the water guide groove 111c, the water in the water guide groove 111c does not enter the housing through the air outlet 111 a.

And an operation panel B having a closed state (closed position) for blocking the water filling port 111B and an open state (open position) for not blocking the water filling port 111B, the operation panel B being connected to the frame 110 by a sliding structure and being switched between the closed state and the open state by a planar motion or a curvilinear motion. By providing the operation panel B having an open state and a closed state, when water needs to be added from the water inlet 111B, the operation panel B can be in the open state, that is, the water inlet 111B is exposed; and after adding water and finishing, operating panel B moves to the closed condition and shelters from the filler to avoid adding water and fall into impurity such as dust or foreign matter in the mouth, prevent that the water that is used for the humidification air from being polluted. The operation panel B may be provided with a sufficiently large area so as to shield the water inlet 111B and the water guide 111c from above the water inlet 111B and the water guide 111c in the closed state. Thus, impurities such as dust and foreign substances are prevented from falling into the water guide groove 111c and flowing into the water filling port 111b along the water in the water guide groove 111c, and the cleanliness of the humidification water can be ensured. When the operation panel B is in a closed state, the humidifying function and the filtering function normally run; when the operation panel B is in the open state, the humidification function of the air purifier stops operating, but the air can still be filtered by the filter unit 130 and then blown out from the air outlet 111a, thereby realizing the filtering function. The operation panel B may partially shield the water chute 111c or completely shield the water chute 111c in the closed state, and the present application is not particularly limited, and it is needless to say that the operation panel B completely shields the water chute 111c as an optimal solution.

In one example, the operation panel B further includes a shielding structure 111 d. In one example, the shielding structure 111d is located at the bottom of the operation panel B.

In the present embodiment, the operation panel B includes the shielding plate 111f in a planar shape, that is, in the present embodiment, the shielding structure 111d includes the shielding plate 111 f. The shutter 111f is switched between the open state and the closed state by sliding. Of course, the shielding plate 111f may also be an arc plate or a bent plate, and the application is not particularly limited, and only the water chute 111c and the water injection port 111b need to be shielded.

The operation panel B is slidably attached to the frame top plate 111, and is switched between a closed state blocking the water filling port 111B and an open state not blocking the water filling port 111B by sliding. Specifically, the operation panel B includes a shielding plate 111f located at the bottom of the operation panel, at least a part of the sliding structure a is slidable on the housing top plate 111, the sliding structure a is connected to the shielding plate 111f, the shielding plate 111f is slid on the housing top plate 111, and the shielding plate 111f is switched between the closed state and the open state by sliding.

The slide structure a includes a base 1, a guide rail 2 (slide guide member), a slide groove 3 (slide member), and a surrounding frame 4 (slide stopper).

The base 1 is disposed on the frame top plate 111, and has a square bottom surface and four side surfaces extending upward from edges of the square bottom surface. A guide rail 2 is fixed in the base 1, the guide rail 2 has a bottom surface accommodated in the base 1, and two side surfaces extending upward from the left and right ends of the bottom surface, and the two side surfaces respectively bend and extend the left and right ends from the vertical direction to the horizontal direction to the outside to form two end surfaces in the horizontal direction. The bottom surface of the guide rail 2 is smaller than the bottom surface of the base 1, so that the guide rail 2 can be fixed inside the base 1 and positioned by four side surfaces of the base 1. The guide rail 2 and the base 1 are both provided with screw holes, and the guide rail 2 can be fixed in the base 1 by penetrating the screw holes in the guide rail 2 and the base 1 through screws. Specifically, a grid composed of a plurality of support ribs is disposed on the frame top plate 111, and a base 1 is disposed on the grid, integrally formed with the support ribs, and disposed along the extending direction of the support ribs.

And an enclosure frame 4 which is provided below the bottom surface of the operation panel (or the lower surface of the shielding plate) and is formed integrally with the shielding plate. In one example, the enclosure frame 4 includes four side surfaces extending from a surface of the operation panel B facing the frame top plate 111 toward the frame top plate 111, and the four side surfaces form a space capable of completely accommodating the slide groove 3. In one example, the enclosure frame 4 includes four side surfaces of an area that may be provided on the bottom surface of the operation panel B to extend in the horizontal direction. In another example, a partial side surface of the enclosure frame 4 including four side surfaces may be provided in an arc-shaped or semicircular region seen from the side surface at both ends of the bottom surface of the operation panel B. As long as the surrounding frame can surround the sliding groove 3 and limit the sliding, the arrangement position and the mode of the surrounding frame 4 are not limited.

And a sliding groove 3 provided below the bottom surface of the operation panel B, wherein the sliding groove 3 includes a top surface fixed in the enclosure frame 4, two side surfaces extending from the left and right ends of the top surface toward the base 1 (i.e., below in the air cleaner mounting state), and two end surfaces bent from the end portions of the two side surfaces of the sliding groove 3 near the base 1 and extending between the two side surfaces in the horizontal direction. The sliding groove 3 is fixed on the bottom surface of the operation panel B extending along the horizontal direction through a screw or a snap structure, so as to drive the operation panel B to move horizontally on the top plate. The slide groove 3 is formed as an open groove having a C-shaped cross section. The lower surface (bottom surface of the operation panel) of the shielding plate and the sliding groove 3 are both provided with screw holes, and the sliding groove 3 can be fixed on the bottom surface of the operation panel B through the screw holes of the shielding plate and the sliding groove 3. Also, the end surfaces of the guide rail 2 may be inserted into the slide groove 3, that is, when the guide rail 2 and the slide groove 3 are engaged with each other, both end surfaces of the guide rail 2 may be surrounded by both end surfaces, both side surfaces and the top surface of the slide groove 3 and slide therein. Since the slide groove 3 is fixed to the lower surface of the shielding plate, the operation panel B is slid together with the slide groove 3, and thus the operation panel B can be slid above the water inlet 111B and the water guide groove 111 c. When the enclosure frame 4 slides to the side surface thereof caught by the guide rail 2, the sliding is stopped, and the operation panel B is placed in the open state or the closed state.

Further, since the height of the four side surfaces of the surrounding frame 4 on the bottom surface of the operation panel B is larger than the height of the two side surfaces and both end surfaces of the slide groove 3, the surrounding frame 4 can cover the slide groove 3, prevent a user from touching the slide groove 3 with a finger to cause a pinch, and improve the appearance of the air cleaner (fig. 2 shows a state where the surrounding frame 4 covers the slide groove 3). In the present embodiment, the bottom surface of the operation panel and the slide groove 3, and the guide rail 2 and the base 1 are fixed by screws, but in actual practice, the fixing method such as engagement may be replaced according to actual circumstances, and the fixing method between the shielding plate and the slide groove 3, and between the guide rail 2 and the base 1 is not particularly limited in the present invention. In addition, since the sliding groove 3 needs to slide back and forth on the guide rail 2, the guide rail 2 can be made of POM material, thereby improving wear resistance. Of course, in actual implementation, other materials can be used, and the material of each component is not particularly limited in this application.

In the present embodiment, two sliding structures are provided in total to ensure smooth sliding of the shutter. The two sliding structures are arranged along the transverse direction or the longitudinal direction of the frame top plate 111, and preferably, the two sliding structures are symmetrically arranged along the transverse direction or the longitudinal direction of the frame top plate 111. Preferably, two sliding structures are arranged along the extending direction of the water chute 111 c. In other embodiments, more than two sliding structures may be provided as needed.

As described above, the slide groove 3 slides along the guide rail 2 so that the shielding face of the shielding plate is parallel to the sliding plane in which the slide groove 3 slides. The distance between the operation panel or the shielding plate and the housing top plate 111 in the closed state is equal to the distance between the operation panel or the shielding plate and the housing top plate 111 in the open state. The distance between the shielding plate and the top plate 111 of the frame body is kept unchanged during the sliding process. The operation panel is located above the frame top plate 111 and blocks the water filling port 111b above the water filling port 111b in the closed state.

In this embodiment, the electrical component inside the operation panel is a touch key circuit board, and a user can conveniently control the functions, modes and the like of the air purifier by operating the touch key circuit board. In other embodiments, the electrical components inside the operating panel may be other types of circuit boards.

A main circuit board box for accommodating electrical components (such as a main circuit board) is arranged at a position outside the air duct inside the frame body. The main circuit board is electrically connected to the operation panel B, the blower unit 120, the humidifier unit 140, and the like via wiring a (see fig. 7). That is, the operation panel B is electrically connected to the components such as the blower unit 120 and the humidification unit 140. After the user operates the operation panel, the operation panel transmits a signal to the main circuit board through the wiring, thereby controlling the components such as the air supply unit 120 and the humidification unit 140 electrically connected to the main circuit board.

In one embodiment, the operation panel B is electrically connected to the air supply unit 120, the operation panel B can display the air speed of the air supply unit 120 and the on state of the air supply unit 120, and the operation panel B can also control the on/off of the single-shaft motor 1202 of the air supply unit 120 and adjust the rotation speed of the single-shaft motor 1202.

In other embodiments, the operation panel B may be further electrically connected to the filtering unit 130, the operation panel B may display the saturation of the filtering unit 130 or the filtering efficiency of the filtering unit 130, and the operation panel B may further adjust the filtering efficiency of the filtering unit 130.

In another embodiment, the operation panel B may be further electrically connected to the humidification unit 140, and the operation panel B may display the amount of the humidification water, and may further control the on/off of the humidification unit 140.

In another embodiment, the operation panel B may be electrically connected to the air supply unit 120, the filtering unit 130, and the humidifying unit 140 at the same time, and the operation panel B may display the air speed of the air supply unit 120, the on state of the air supply unit 120, the saturation of the filtering unit 130, the filtering efficiency of the filtering unit 130, or the amount of the humidifying water, and may control the on/off of the single-shaft motor 1202, adjust the rotation speed of the single-shaft motor 1202, adjust the filtering efficiency of the filtering unit 130, and adjust the on/off of the humidifying unit 140 at the same time.

In other embodiments, the air purifier may also include sensors such as a humidity sensor, a temperature sensor, a dust detector, and a water level sensor, which are electrically connected to the operation panel B, and the operation panel B may display data such as humidity, temperature, and dust amount according to detection results of the sensors.

The respective components for fixing and guiding the wiring of the present invention will be described below with reference to fig. 7 to 12.

Referring to fig. 7 and 10, the air purifier includes: and an operation panel B. The operation panel B is movably provided above the housing top plate 111 of the housing 110, and electric components inside the operation panel B are connected to one end of the wiring, and electric components inside the housing 110 are connected to the other end of the wiring.

The air purifier still includes: a wiring harness fixing member 150. The wiring fixing member 150 is provided in the operation panel B, and fixes a portion of the wiring extending inside the operation panel B. In one example, the wiring fixing member 150 may not be provided. Only the wiring guide assembly 160 needs to be provided to achieve one of the objects of the present invention.

The air purifier still includes: wire guide assembly 160. The wiring guide assembly 160 includes: a guide hole 161 penetrating the bottom surface of the operation panel B, and a guide 162 at least partially disposed in the guide hole 161, the guide hole 161 extending in a predetermined direction and the guide hole 161 and the guide 162 being relatively displaced with the movement of the operation panel. In one example, the guide hole 161 is adjacent to the wire harness securing assembly 150. In one example, when the guide 162 is moved to be in contact with or adjacent to one end portion of the extending direction of the guide hole 161, the operation panel B is in a first position (open position), and when the guide 162 is moved to be in contact with or adjacent to the other end portion of the extending direction of the guide hole 161, the operation panel B is in a second position (closed position), and the wires are connected to the electric components inside the operation panel B and the wire fixing unit 150 in turn, and connected to the electric components inside the frame 110 after passing through the guide 162 of the wire guiding unit 160.

Of course, since whether the operation panel B is in the open position or the closed position is defined by a sliding structure or the like, the guide 162 may or may not be in contact with the end of the guide hole 161 (i.e., spaced a predetermined distance from the end of the guide hole 161) when the operation panel B is in the open position or the closed position.

In one example, the guide hole 161 is an elongated hole, the length direction of which is parallel to the moving direction of the operation panel B. The elongated hole is formed by two flanges which are arranged along the length direction and protrude from the bottom surface of the operation panel B to the lower side. One of the flanges is a side edge of the surrounding frame, and the other flange is arranged opposite to the side edge of the surrounding frame.

The first wire outlet 151 is provided at a position closer to the electric components inside the operation panel B than the position of the elongated hole.

Referring to fig. 11 and 12, the air deflector C is located below the top plate of the frame body inside the frame body. The air guiding plate C is provided with a wire inlet groove 1621 arranged along the vertical direction, the wire inlet groove 1621 is a part of the guiding member 162, an opening at the end part of the upper end of the wire inlet groove 1621 forms a second wire outlet 1622, and the second wire outlet 1622 extends into the elongated hole and can move in the elongated hole. That is, the wire inlet groove 1621 on the air guiding plate C is extended upward and sandwiched by two flanges of the elongated hole, so that the wire inlet groove 1621 can move together with the second wire outlet 1622 along the extending direction of the elongated hole with respect to the elongated hole, wherein what actually causes displacement is the operation panel and the elongated hole on the operation panel. Of course, referring to fig. 7 to 10, the guide 162 may be integrally provided on the frame top plate 111, one end of the guide 162 is disposed in the guide hole 161, the other end of the guide 162 is connected to the frame top plate 111 and extends through the frame top plate 111 into the frame 110, an opening of the one end of the guide 162 disposed in the guide hole 161 constitutes a second wire outlet 1622, and the wire enters the guide 162 through the second wire outlet 1622.

As described above, the guide 162 may be provided on the frame top plate 111 or may be provided on the air guide plate C.

Referring to fig. 7, 10 and 11, the wiring fixing member 152 is disposed between the first wiring outlet 151 and the second wiring outlet 1622. Since two points are fixed to a straight line, the first wire outlet 151 and the wire fixing member 152 can prevent the portion of the wire between the first wire outlet 151 and the wire fixing member 152 from moving during the movement of the operation panel B, thereby preventing the wire from being twisted.

In one example, the wiring fixing member 152 is a clip, and in another example, the wiring fixing member 152 is a clip, and is located on a midperpendicular of a straight line on which the longitudinal direction of the elongated hole is located, that is, in the vicinity of an area disposed on the bottom surface of the operation panel B in the middle of both end portions of the guide hole 161 in the extending direction of the guide hole 161. The lengths of the portions of the wires between the clip and the second wire outlet 1622 are made to be the same in both states of the operation panel, and the wires are prevented from being twisted. Specifically, it is assumed that a straight line is drawn along the length direction of the elongated hole, and then straight lines are drawn from the wire clip to both end portions in the length direction of the elongated hole, the three straight lines form an isosceles triangle having the straight line in the length direction of the elongated hole as a base, and the wire clip is located on a perpendicular bisector of the base. The wires are led out from the terminals of the touch key circuit board, and then sequentially pass through the first wire outlet 151, the wire clip, and the second wire outlet, and then are connected to the main circuit board inside the housing 1622.

With the above structure, after the wiring a is led out from the terminal of the touch key circuit board and passes through the first wiring outlet 151 and the wire clip, the section of wiring located between the first wiring outlet 151 and the wire clip is fixed in position by the first wiring outlet 151 and the wire clip. No matter the operation panel B is in the closed state or the open state, the wire clip and the first wire outlet 151 slide together with the operation panel B, that is, the relative positions of the wire clip and the first wire outlet 151 do not change, so that the wire between the first wire outlet 151 and the wire clip is always positioned by the wire clip and the first wire outlet 151, and other parts cannot be clamped due to the sliding of the operation panel B.

Referring to fig. 8, when the operation panel B is in the closed state, the second wiring outlet 1622 is adjacent to one end portion of the elongated hole; referring to fig. 9, when the operation panel B is in the open state, the second wiring outlet 1622 is adjacent to the other end portion of the elongated hole. Since the distance between the wire clip and the two ends of the elongated hole is equal, after the wire is led out from the wire clip, although the length of the wire between the wire clip and the second wire outlet 1622 moves along with the sliding of the operation panel B, when the operation panel B is in the closed state and the open state, the length of the wire does not change or the difference is not large, so long as the wire which is slightly longer than the distance between the wire clip and the any end between the wire clip and the second wire outlet 1622 is reserved to move between the wire clip and the second wire outlet 1622, the wire between the wire clip and the second wire outlet 1622 can not fall into the frame and be hooked by the internal components of the frame when the operation panel B is in the open state or the closed state due to overlong, thereby protecting the wire and ensuring the service life of the wire.

Further, as described above, since the wiring a is always located in the operation panel B or the wiring groove 1621 during the sliding of the operation panel B after being led out from the terminal on the touch key circuit board, even if there is liquid on the operation panel B or between the operation panel B and the housing top plate 111, the liquid cannot flow to the wiring, and thus the water is prevented from flowing to the electric components along the wiring, thereby achieving a waterproof effect.

In addition, the wire clip comprises a first concave-convex block 1521 and a second concave-convex block 1522 which are parallel to the moving direction of the operating panel B, the first concave-convex block 1521 and the second concave-convex block 1522 are oppositely arranged, the first concave-convex block 1521 comprises two or more first convex ribs 1521a which are extended towards the second concave-convex block 1522 and are mutually spaced, the second concave-convex block 1522 comprises two or more second convex ribs 1522a which are extended towards the first concave-convex block 1521 and are mutually spaced and are arranged in a staggered mode with the first convex ribs 1521a, a space for a wire to pass through is formed in a gap between the first convex ribs 1521a and the second convex ribs 1522a, and the wire is inserted into the wire clip from the upper side of the wire clip. In order to stably fix the wiring, it is preferable that the smaller the gap between the first concave-convex block 1521 and the second concave-convex block 1522 of the clip is, the better the gap is, and it is preferable that the wiring is interference-fitted in the gap between the first concave-convex block 1521 and the second concave-convex block 1522. However, if the gap is too small, it is difficult to insert the wiring into the gap between the first concave-convex block 1521 and the second concave-convex block 1522 from above the clip. Therefore, instead of directly sandwiching the wiring by the first concave-convex block 1521 and the second concave-convex block 1522, two or more first ribs 1521a are provided at intervals in a direction of the first concave-convex block 1521 facing the second concave-convex block 1522, two or more second ribs 1522a are provided at intervals in a direction of the second concave-convex block 1522 facing the first concave-convex block 1521, and the wiring is sandwiched by a gap between the first ribs 1521a and the second ribs 1522 a. Even if be interference fit between clearance and the wiring between first protruding muscle 1521a and the second protruding muscle 1522a, nevertheless because interval each other between the first protruding muscle 1521a, interval each other between the second protruding muscle 1522a, and stagger the setting between first protruding muscle 1521a and the second protruding muscle 1522a, so the wiring can insert the clearance between first protruding muscle 1521a and the second protruding muscle 1522a more easily to improve assembly convenience.

Furthermore, a separation plate D is arranged between the wire clip and the touch key circuit board inside the operation panel B, a flat plate E perpendicular to the separation plate D is arranged on the bottom surface of the operation panel B, a first wire outlet 151 is formed in a gap formed between the end of the separation plate D and the flat plate E, and the first wire outlet 151 is located on the opposite side of the touch key circuit board inside the operation panel B with the separation plate D as a boundary. That is, the first wiring outlet 151 and the touch key circuit board are respectively located at both sides of the separation plate D, separated by the separation plate D. Thus, the wiring can be positioned by the first wiring outlet 151 and the wire clip after being led out from the touch key circuit board, and is separated from the touch key circuit board through the separating plate, so that the wiring is prevented from being cut and damaged by the edge contact of the wiring and the touch key circuit board, and the service life of the lead is ensured.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same. The scheme of the utility model is suitable for other devices for humidifying gas.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
